Azért lehet ezt-azt találni a 8500-ról :

"In an admirable show of honesty, Mr. Monachon also cautioned us that although the calibre 8500/8501 are completely designed and developed within OMEGA Granges, it is dangerous to call the movement completely in-house manufactured. Without the help and assistant of Comadur, Nivarox, ETA and Frederick Piguet – all within the Swatch Group, the success of this calibre and the Deville Hour Vision model would not have been possible. The objective is to manufacture the complete movement and watch within OMEGA premises but at the moment, only assembly is done within the OMEGA compound."
